   * A marker interface for all operation wrappers.

   * without the use of literals and indexes, as required in the core classes.
   *
   * <p>This interface allows keeping references to any operation wrapper using a common type.
   *
   * <pre>{@code
   * // All values returned by an Ops call can be referred as a Op
   * Op split = ops.array().split(...);
   * Op shape = ops.array().shape(...);
   *
   * // All operations could be added to an Op collection
   * Collection<Op> allOps = Arrays.asList(split, shape);
